... answers to most of my questions What's their origin? And did "first cell" contain genes for them? What if there would be a mutation and and some chaperonin would be nonfunctional? Would it be lethal? now I read that ribosomes in prokaryotes don't have chaperonins function so it would be lethal ...

I have some questions about chaperonins and protein folding... 1.How do chaperonins help folding the polypeptide chain(know about hydrogen bonds but mechanism...)? like enzyme?What's their origin? And did "first cell" contain genes for ...

yeah and are you talking about chaperone proteins such as chaperonin which helps a protein take its final formation?
